Fan system

摘要

A fan system suitable for an electronic device is provided. The fan system includes a fan module and a fan protecting module. The fan module includes a base and a fan blade assembly. The base is disposed at the electronic device and has a chamber. The fan blade assembly includes a fan blade and a shaft portion. The fan blade is fixed on the shaft portion. The shaft portion is rotatably contained in the chamber. The fan protecting module includes an electromagnetic component and an accelerometer. The electromagnetic component is disposed at a position adjacent to the shaft portion. The accelerometer is disposed in the electronic device and coupled to the electromagnetic component. When an acceleration of the electronic device detected by the accelerometer is greater than a threshold value, the electromagnetic component applies magnetic force to the shaft portion to prevent the shaft portion from overly shifting or deflecting.

主权项

1. A fan system suitable for an electronic device, the fan system comprising:
a fan module comprising:
a base disposed at the electronic device and having a chamber; anda fan blade assembly comprising at least one fan blade and a shaft portion, wherein an end of the at least one fan blade is fixed on the shaft portion, the shaft portion is rotatably contained in the chamber so that the fan blade assembly is adapted to rotate relative to the base around the shaft portion, and at least one first end of the shaft portion comprises a material attractive to magnetic force; and a fan protecting module comprising:
an electromagnetic component disposed at a position adjacent to the first end of the shaft portion and outside the chamber, wherein the electromagnetic component is located on a rotation axis of the shaft portion; andan accelerometer disposed in the electronic device and coupled to the electromagnetic component, wherein when an acceleration of the electronic device detected by the accelerometer is greater than a threshold value, the electromagnetic component generates a magnetic force applied to the first end of the shaft portion to prevent the shaft portion from overly shifting or deflecting.
